How to Avoid Capital Gains Tax on Investment Property in Australia (2026)

You can legally reduce or sometimes avoid capital gains tax on investment property by using the 50% CGT discount, the main residence exemption, cost base records, capital losses, and careful sale timing.

Most pure rental properties still create a taxable capital gain when sold for a profit. The aim is to reduce the taxable amount before it reaches your income tax return.

Use the PropBoss capital gains tax calculator before listing or signing a contract so you can model the likely tax payable.

Do You Pay Capital Gains Tax (CGT) on Investment Property?

Yes. If you sell an investment property for more than its cost base, the profit is a capital gain and you may need to pay capital gains tax.

The Australian Taxation Office (ATO) treats the gain as part of your assessable income for the financial year when the contract is signed, not when settlement occurs.

Capital gains tax is not a separate tax rate. Your net capital gain is added to your taxable income and assessed at your marginal income tax rate.

CGT applies to real estate acquired after 20 September 1985. A property acquired before that date is generally a pre CGT asset.

How to Avoid Capital Gains Tax on Investment Property: Key Strategies

You usually cannot avoid capital gains tax completely on a property that was always rented out. You can, however, reduce capital gains tax with several legitimate strategies.

The best result usually comes from combining more than one strategy before the sale contract is signed.

Use the 50% CGT Discount

The 50% CGT discount is the most common way Australian residents reduce CGT.

If you hold the asset for at least 12 months before the CGT event, you generally pay tax on only half of the capital gain.

For example, a Brisbane investment property bought for $550,000 and sold for $720,000 has a $170,000 gross capital gain before costs.

After the CGT discount, only $85,000 is added to assessable income. At a 37% marginal rate, that is about $31,450 of tax instead of $62,900.

Check the Main Residence Exemption

The main residence exemption can eliminate CGT if the property was genuinely your home and you meet the rules.

Under the six year absence rule, a former home can keep its main residence status for up to six years while it is rented, as long as you do not nominate another home for the same period.

Prove It Was Your Genuine Home

The ATO looks for practical evidence. Electoral roll address, mail, utilities, personal belongings, and family use all help show the dwelling was your primary residence.

Briefly moving into a rental property just to claim the exemption is high risk.

Use a Partial Exemption After Six Years

If the rental period runs beyond six years, only a partial exemption may apply.

The taxable portion is usually based on the number of days the property was not covered by the main residence exemption compared with the entire ownership period.

Reduce Gains Tax by Maximising Your Cost Base

Your cost base is the purchase price plus eligible acquisition, holding, improvement, and selling costs.

A higher cost base means a lower capital gain or loss. That directly reduces the amount of gains tax included in your tax return.

Include Purchase and Sale Costs

Cost base items commonly include stamp duty, legal fees, buyer's agent fees, building inspections, advertising, auctioneer fees, and selling agent commission.

On a $700,000 sale, a 2% agent commission is $14,000 that can reduce the capital gain.

Add Capital Improvements

Capital improvements are different from repairs. A new kitchen, bathroom renovation, extension, or structural upgrade can increase the cost base.

If you spend $45,000 on a kitchen renovation before selling, that $45,000 can reduce the taxable gain. With the 50% discount and a 37% marginal rate, the tax saving can be about $8,325.

Repairs such as fixing a leaking tap are usually claimed against rental income when incurred, not added to the CGT cost base.

Keep Depreciation Records

A depreciation schedule can help separate capital works from repairs and plant items.

Capital works deductions under Division 43 may affect the cost base, so keep the quantity surveyor report and annual tax return records.

Use the PropBoss depreciation estimator to understand how depreciation can interact with a future CGT calculation.

Offset a Capital Loss

A capital loss from shares, cryptocurrency, managed funds, or another property can offset a capital gain.

Capital losses are applied before the 50% discount, which makes them valuable.

Unused losses can carry forward indefinitely. A loss from five years ago may still reduce CGT when you sell today.

Time the Sale to a Low-Income Year

Because the net gain is added to taxable income, timing the sale can matter.

Selling in a lower income year, such as retirement, parental leave, or a career break, may push part of the gain into a lower tax bracket.

For tax purposes, the key date is the contract date. A contract signed on 28 June falls in a different financial year from one signed on 2 July.

Use Super for Investment Income Planning

Concessional super contributions can reduce taxable income in the year of sale, subject to contribution caps and eligibility.

In 2025-26, the concessional cap is $30,000. Salary sacrifice or a deductible personal contribution can help manage the marginal tax rate applied to the gain.

Watch Foreign Resident and Non Resident Rules

Foreign residents and many non residents cannot claim the 50% discount on Australian property gains.

They may also lose access to the main residence exemption except in limited life event cases.

If you are moving overseas, compare selling before and after residency changes.

Consider Small Business CGT Concessions

Small business CGT concessions may apply if the property is an active business asset, such as a shop, warehouse, or office used in your business.

Common thresholds include aggregated turnover under $2 million or net CGT assets under $6 million.

Available concessions can include the 15-year exemption, 50% active asset reduction, retirement exemption up to $500,000, and rollover relief.

Review Trusts and Ownership Structure

If a family trust owns the property, the trustee may be able to distribute a capital gain to beneficiaries according to the trust deed.

That can create tax flexibility, but trust streaming rules are technical and the ATO reviews artificial distributions closely.

The CGT discount can still be available to some trusts, but not every structure qualifies in the same way as an individual owner.

Check Life Events Before You Transfer

Relationship breakdown, death, and inherited property can change the CGT outcome.

A transfer to a former spouse under a court order or binding financial agreement may receive rollover relief, so no immediate CGT event occurs.

Inherited property has special cost base rules. The answer depends on whether the deceased acquired it before or after 20 September 1985 and whether it was rented.

Cost Base Checklist

Check these records before you calculate CGT:

• Contract price and settlement statement
• Stamp duty paid on purchase
• Conveyancing and legal fees
• Buyer agent, inspection, and valuation costs
• Renovation invoices and capital improvements
• Selling agent commission and advertising
• Depreciation and capital works schedules
• Carried forward capital loss records

Capital Gain Worked Example

Mark bought a Sydney property for $650,000 in 2020 and sells it in 2026 for $850,000.

His cost base includes $26,000 stamp duty, $4,500 legal fees, $35,000 of capital improvements, and $17,000 selling commission.

That creates a total cost base of $732,500 and a gross capital gain of $117,500.

Because Mark held the property for more than 12 months, the 50% CGT discount reduces the taxable capital gain to $58,750.

If Mark's other income is $95,000, his total taxable income becomes $153,750 before other deductions.

Planning Ahead to Minimise CGT

Start planning before the property is listed, not after contracts are signed.

Keep receipts from day one, track the market value of each asset, and review possible capital losses before the financial year ends.

Ask your accountant to model at least two sale years if your income is changing.

Small timing changes can alter tax, cash flow, borrowing capacity, and future investment options.

Before you sell, make a short decision file for the property.

Record when you started renting it, when renting stopped, and whether the six year rule was used for any period.

List every asset you may sell in the same year, including shares, managed funds, crypto, and other investments.

That review helps property investors decide whether to claim deductions now, carry losses forward, or sell investments with a loss in the same financial year.

Also note council rates, insurance, interest, repairs, and other expenses so your accountant can separate tax deductions from cost base items.

If you want to pay CGT correctly but keep more money after tax, seek professional advice before you sign.

Good expert support should compare your current home versus the rental, confirm your primary place of residence evidence, and check any super balance limits.

Common scenarios that need extra care include moving interstate, earning rent from a family home, and trying to sell one property while buying another.

These records help you meet tax obligations, prove eligibility, and avoid costly mistakes if the ATO asks questions later.

FAQs

How Much CGT Do You Pay on Property?

It depends on your cost base, holding period, capital losses, residency, and marginal tax rate. Many Australian residents who hold for more than 12 months pay tax on half of the gross gain after costs.

Can You Completely Avoid Capital Gains Tax on Property?

You may avoid CGT if the property is fully covered by the main residence exemption. A property that was always rented usually cannot eliminate CGT completely.

What Costs Reduce Capital Gains Tax CGT?

Purchase price, stamp duty, legal fees, eligible holding costs, capital improvements, and selling costs can reduce the capital gain.

Do Foreign Residents Pay More?

Often, yes. Foreign residents usually cannot claim the CGT discount and may have limited access to the main residence exemption.

Can a Capital Loss Reduce CGT?

Yes. A capital loss can offset capital gains before the discount is applied, and unused losses can carry forward to later years.

Avoid Capital Gains Mistakes Before You Sell

The biggest mistakes are selling before the 12 month discount, losing renovation records, ignoring the contract date, and assuming a former home is automatically exempt.
